In the environs of the city of Ipolca, today’s town of Porcuna (Jaén), the Iberian civilisation left behind one of the most outstanding sculptural ensembles of Antiquity, made up of 27 groups of figures and hundreds of fragments dating from the 7th to the 2nd centuries BC. Despite its great relevance, there are very few scientific studies that serve as a basis for understanding the many questions that remain about how they were made, their significance, and their relationship to the culture that gave rise to them. This article studies the polychrome techniques used in the sculptures and puts them into context in Iberian art. The research has been carried out on original pieces from the Archaeological Museum of Jaén using stereoscopic optical microscopy (SOM), petrographic microscopy (PM), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopyenergy dispersive X-ray analysis (SEM-EDX). 2023-11-29T13:00:29Z 2023-11-29T13:00:29Z 2023-10-20 journal article Romero-Noguera, J.; Ruiz-Ruiz, M.B.; Doménech-Carbó, M.T.; Bolívar-Galiano, F.
